Elementary School Science Teacher Guide

(PS-2875D)

Features 29 inquiry based labs designed for elementary students and coordinated with the standards for life, earth and physical sciences.

Investigating Sound Levels

Lab Summary

Students recognize that continuous sound is made by vibrating objects, and can be described by its pitch and volume. Students explore different continuous sounds by studying the changing volume.

Method

To understand this content, students:

  • Describe sound volume using drawings and verbal descriptions.
  • Hum in a variety of ways near the sound sensor and test the effect of a "megaphone".
  • Compare graphs of sound levels and draw conclusions about sound and vibration.

Sensors / Equipment Used:

PASPORT Temperature/Sound Level/Light Sensor

(PS-2140)

Allows students to conduct all three measurements simultaneously and continuously. For use with PASPORT Interfaces.

PASPORT Sensor Extension Cable

(PS-2500)

Allows an additional two meter length extension on all PASPORT sensors.

Materials Used:

Sheet of paper to make a sound tube, 21-cm × 28-cm (8.5-in. × 11-in.)

The Associated Bundle:

Elementary School Science Standard Sensor Bundle

(PS-2934)

This bundle contains the probeware needed to perform all 25 lab activities in the Elementary School Introductory Science Experiments.

Interface Required

This experiment may require software and an interface for data collection.
